The passage around this formula

…As v ≪\ll c and the wavepacket is restricted to the positive-energy subspace, the oscillating term’s amplitude falls relative to the packet’s own spatial width, and x^\hat{\mathbf x} , XNW\mathbf X_{\mathrm{NW}} , and RN\mathbf R_N converge onto one description — the same nonrelativistic recovery checked twice already, confirmed here a third time from an entirely different starting operator.
